To aZZauhomz'tmaycomem:

Be it known that'we, GAsroN A. GUYor and ARTHUR 'F. .GUYoT, citizens of the United States, residing, at Attleboro, in the countyiof Bristol and State of Massachusetts, haveinvented certain new.and useful Improvements 7 in a WatCh-BraceIet Hook, of which the following is a specificationl '1 This invention relates to improvements in the construction of hooks or claspsmore particularly adaptedfor use in releasably connecting the ends of a bracelet to the opposite sides of a wristwatch, and the object of this invention is to provide .such

a hook having a body portion which comprises front and back members connected by a pair of widely-separated joint portions which are folded so as to engage and support each other a substantial distance inward from the bend whereby the constant opening and closing of thehook will not tend to weaken the stock at the fold, the free end of one of the members being pro- 2 vided with a hook which is closed by tension of the opposite member resting. against its end. I

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. 6. V v,

In the accompanying drawings, Figure 1 is an edge view of a watch show ing our improved'st'rap-hook as attached thereto. I p A Figure 2 is a front-viewofour improved hook showing the spaced apart-portions which connect the front and back members of the hook.

Figure 3 is a back view of the hook show-' ing the slot through which the strap is passed. 1 V Figure lis a sectional edge view-of the hook illustrating the strap in dotted lines as passing through openings, in both the front and back members of the hook; also showing the hook member as beingvided with an open loop at the fold and the parts supporting each other a substantial distance inward from the fold.

Figure 5 is a modification illustrating the back and front members of the hook as closed upon itself atthefold for a substanprospaced apart joint portions folded so that the. o

tial distance inward from the extremity xpf thefold; 1

It isfound in practice that where ahook or other member formed of a single piece of sheet metalis folded upon itself .infan open fold that the constant working'of the parts soon-crystallizes the metal atgthe-fold' causing itto break at this point, and the following v.is ajdetailed description of one construction of hook ;,rnember which will prevent the bending of the stock at the fold each timethe hook members are operated and so prevent breakage at this point and consequently greatly extending the operating life of the device.v j

With reference to the drawings, 10 designates the front plate of the hook and 11 the back plate thereof both of which are connected together and are formed of a single piece of sheet stock folded upon itself. Themiddle portion of the stock at the fold is cut away as at l2providing a pair of widely-separated p0I'ti0I1s13 connecting the front and back members. These joint portions are. preferably folded into an open loop shaped as illustrated at 14 in Figure Land the sides of the front and back members are turned inwardly to en gage each other at 15 at a point a substantial distance inward from theextremity 16 of the bend.

. The upper or free end of the back plate is provided with'a tongue 17 which is bentv over into hook form to lay against the outside surface of .the projection 18 on the front plate 10. Both the front and back plates are provided with. registering opening-s19 through which a strap. or ribbon20 of the bracelet;

or band may pass.

In'so'me instances instead of folding the stock at the. bend into loop form as illus-, trated in Figure 4:,we fold this stockback upon itself as at 21- in Figure'5fwhereby it i is caused to support itself'for a substantial distance inwardly from the extremity of .100-

the fold. r

By our improved construction of hook member which is provided with widelyfront and back portions will engage and suppoi-teach other a substantial distance inward from the bend, the stock at thefold'is, pre-v vented from being bent each time the hook is opened and closed thereby greatly increasing t-he wearing life of the hook and giving greater resiliency to its action.

The foregoing description is directed solely towards the construction illustrated, but we desire it to be understood that we reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms 05 the appended claims.

W'Ve claim: I I

1. A Watch bracelet hook formed of a single piece of stock comprising front and back body members connected by a pair of. widey -separated joint portions folded to engage and snpport-eachother a substantial distance inward from the bend, a yieldable tongue on the free end-of one of said members bent into hook form and the opposite member bein adapted to close said hook by the inherent spring at the joint, said members being provided with a strap-receiving opening. I o

2. A Watch bracelet hook formed of a single piece of folded stock comprising front and back body members connected by widely-separated" resilient joint portions folded into open loop form, each being shaped to engage and support each other at a point a substantial distance inward from the bend, a yieldable tongue on the free end of one of said members bent into hook form and the opposite member being adapted to close said'hook by the inherent spring at the joint, both of said members be ing provided with registering strap-receive ing openings. I

In testnnony whereof we affix our s1gna-' tnres.
